I thought I saw somewhere that someone had said the newer S9's did not use the beaglebone any longer.
there are two styles of controller:
bitmainwarranty has second model which is a slotless sdcard all in one board.
it can be pulled if dead.
and you can use the first controller for batch one is two piece sdcard slotted and will run my newer boards.
I have used the two piece unit to run the batch nine boards.
my error was cause by a lack of photos on their website.
But not to worry I have come up with an idea to mod the s9.
I will be waiting for new parts and replace the dead 1 card board with a 2 piece older board.
